Hair brush

ABSTRACT

A kind of hairbrush that contains bristles spot welded with granular tips at outer end (the end in contact with hair and scalp). The granular tips are made of plastic material admixed with powder mixture of extreme infrared radiation material and poly-element minerals.

BACKGROUDN OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to hairbrushes.

[0003] 2. Background Information

[0004] U.S. Pat. No. 6,357,075 relates to a hairbrush that contains bristles formulated with powder formed from the mixture of both extreme infrared radiation material and poly-element minerals, which are then mixed into a plastic material and attached to a bristle base of the hairbrush to stimulate circulation of the scalp so as to promote hair growth and provide scalp care.

[0005] The bristles of conventional hairbrushes may be made of plastic or metal material. In the case of metal bristles, U.S. Pat. No. 6,357,075 does not apply.

[0006] It is also universally known that when you brush hair, only the tip of the bristles of the hairbrush touches the scalp. In the invention under U.S. Pat. No. 6,357,075, the entirety of the bristles is added with mixture powder, which results in waste of powder material and might affect the strength and performance of the plastic bristles.

SUMMARY OF THE INVENTION

[0007] The present invention addresses the shortcomings of U.S. Pat. No. 6,357,075, and in concurrence with the suitability of metal bristles, proposes a kind of hairbrush that contains plastic or metal bristles having granular tips. Said granular tip is formulated with mixture of extreme infrared radiation material and poly-element minerals, both in powder form, which are then mixed into plastic material and spot welded onto the outer end of bristles (the end that is in contact with hair and scalp). The granular tip is rounded in shape and thus will not hurt the scalp when bristles are in contact with the scalp. On the other hand, the bristles of such a hairbrush with granular tip use much less extreme infrared radiation material and poly-element minerals and retain their original strength and performance.

BRIEF DESCRIPTION OF THE DRAWING

[0008] The accompanying drawing is provided for the purpose of illustration only, and is not intended as a definition of the limits of the invention. The drawing schematically illustrates a preferred embodiment of the present invention, in which:

[0009]FIG. 1 is a perspective view of a hairbrush employing the preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0010] Referring to FIG. 1, the preferred embodiment of the invention herein consists of a hairbrush 1 comprising a handle 10, a bristle base 11, and plurality of bristles 12 attached to or inserted into the bristle base 11, in which handle 10 and bristle base 11 are made of plastic material, whereas bristles 12 may be made of plastic or metal.

[0011] Granular tips 121 in spherical shape are spot welded onto the outer end of bristles 12 and made of plastic material formulated with mixture of extreme infrared radiation material and poly-element minerals. When the plastic material admixed with extreme infrared radiation material and poly-element minerals is still in liquid state before solidification, it is spot welded onto the outer end of bristles 12 and in granular shape when it solidifies. The round and smooth surface of granular tips 121 can protect the scalp from sharp bristles. The bristles 12 use only small amount of mixture of extreme infrared radiation material and poly-element minerals and retain their original strength and performance.

[0012] Furthermore, the powder mixture of extreme infrared radiation material and poly-element minerals does not have to be limited to 1˜3% of the volume of the plastic granular tip. It may go up to 20%˜30% or even higher without adversely affecting the original strength and performance of the bristles. In other words, if the ratio of power mixture in the granular tip is increased, the bristles stimulate blood circulation of scalp even better through the actions of extreme infrared radiation material and poly-element minerals to promote hair growth and provide scalp care and create beautiful, shiny hair.

[0013] The ingredients and their blending ratio in the powder mixture that forms the granular tip of bristles 121 are listed below: SiO₂ 36.00˜39.00% Al₂O₃ 31.00˜34.00% CeO₂  9.00˜11.00% P₂O₅  7.50˜9.00% La₂O₃  4.00˜5.20% Pr₆O₁₁  0.96˜1.05% TiO₂  0.95˜1.05% ZrO₂  0.75˜0.85% Y₂O₃  0.60˜0.70% Fe₂O₃  0.55˜0.65% K₂O  0.37˜0.43% CaO  0.30˜0.35% Ag₂O  0.20˜0.30% MgO  0.06˜0.08% SO₃  0.04˜0.05% Na₂O  0.03˜0.04% MnO  0.03˜0.04%

[0014] As for issues, such as that the static electricity generated during hair brushing may be prevented by adding carbon to the granular tip 121 or bristle 12, or whether the hairbrush 1 may be used independently or together with a hair dryer does not fall within the scope of this invention and are not strictly confined here.

[0015] The description of the drawing above presents merely a preferred embodiment of this invention and is not meant to limit the applications of this invention. All modifications or equivalent variations in line with the spirit of this invention should be included in the claims of the invention herein. 

1. A hairbrush comprising: a handle; a bristle base; and a plurality of plastic or metal bristles having plastic material containing powder mixture of extreme infrared radiation material and poly-element minerals spot welded to their tips before said plastic material solidifies into granular shape; the granular tips with round and smooth surface protect the scalp from possible harm of bristles and use only small amount of powder mixture containing extreme infrared radiation material and poly-element minerals without affecting the original strength and performance of the bristles.
 2. A hairbrush according to claim 1, in which the powder mixture of extreme infrared radiation material and poly-element minerals is not limited to 1˜3% of the volume of the plastic granular tip, but may go up to 20%˜30% or even higher without adversely affecting the original strength and performance of the bristles; once the ratio of power mixture in the granular tip is increased, the functions of bristles to promote hair growth, provide scalp care and create shiny hair by stimulating blood circulation of scalp through the actions of extreme infrared radiation material and poly-element minerals are greatly enhanced.
